Chinese slackline athlete Shi Hailin took on a terrifying challenge at Tiger Leaping Gorge in southwest China, balancing above the raging Jinsha River. Shi crossed 328 feet of a 656-foot slackline while powerful canyon winds sent the narrow line swinging beneath his feet. The extreme stunt took place on a slackline just 1 inch wide, forcing him to constantly adjust his balance as the river roared far below. #china #slackline #viral #world
